The biodiversity and distribution of penguin species in the antarctic peninsula are changing as sea ice disappears. this is most likely caused by what factor?

climate change
severe weather
decreasing oxygen levels in the ocean
increasing acidity levels in the ocean

Climate change

Explanation:

Penguin are flightless birds which are found in the cold regions of the earth like Antarctica. They are adapted to survive in the cold environmental conditions.

Climatic change is the factor which affect the biodiversity and distribution of the penguin species. If due to global warming the temperature of the Antarctic region melts the glaciers will melt and penguins will loss their habitat and will not survive in rising temperature ranges.
